local_conf is an array. An assosiative array in Perl, is called a hash.

Dear Tim,
I think your code is on the right track, as I got a modified
version of your code working. I never use getc...
In C, where getc originates, the getc function returns a
char type. The C char type is almost always 8 bits long.
By definition it doesn't support unicode, so neither does

Hi!
Yes, you are near of the truth :). But if I use some complicated joining
query to few large tables I think this is not too comfortable for the
server.

I've got a function which checks that only allowed characters are

yes, i read these man pages more than just one time now (at different times),
so i think i should have not missed anything.

I don't think there is a way to make fetchrow_array() reverse the sequence
in which it delivers data. You can always store the data in a variable if
you need to use it later. Otherwise, if you are receiving rows of data from
the database in an order that makes it hard to work with you may want to t
Thanks Jonathan and Bob! From studying both your answers (for quite a
while), I actually get what this code is doing.
You guys are awesome. (I'm a newcomer.) Hope to give back some day...

Hi,
Not had the misfortune to need to play with this stuff, but I guess
the documentation for perl is a good place to start:
perldoc perl
Particularly:
perldoc perluniintro
perldoc perlunicode
Some aspects are version dependent, so make sure your script
insists on a minimum version of perl.

If no files are specified, then pretend we got /var/yp/src.

Hello there!
I have some dataset got by the executing of some query. For example:
my $sth = $dbh->prepare('select * from sometable');
$sth->execute();
Going through this dataset by $sth->fetchrow_array() I need to go back
inside this proccess. Sorry, but I have no idea how can I do this. How

Hello,
i have intensively searched the web for a solution on the following problem,

The following code does basicelly nothing else then reading in a file on single

thanks for the input. Actually I wanted to provide more details but I
thought there would be a simple and standard solution for it (that I
hadn't found.)

Not in a useful way.
